Drain Pump Theory of parts - >
Check the machine part
1. If the electric part is OK, we need to check the machine part.
2. Remove bottom board.
3. If the non-return valve is wrongly assembled, the tub will remain much water. We need to
re-assemble the non-return valve.
4. If the drain pump is working, but no water drain out or just a little. We should check the
drain hose or drain body.
1. Drain off the water in the dishwasher, and
disconnect the power supply
(Note : Make sure to remove remained water in the
dishwasher. If not, wet the floor.)
2.Loosen the hooks, and then remove bottom
board.(Note:You should first loosen the top hooks,
then the left and right hooks. and be care do not
break the hook.)
3. Label and disconnect the two terminal lugs from
the drain pump.
4. Contrarotate the drain pump to take it off.
5. Reverse the above procedure to install.
。
Access drain pump
Inspect drain pump
Check the electric part
1.Open the protecting box and take out the PCB;
2.With the door closed,unplug the CON3 and ACN wires,
then use the multi-meter
shelf to measure the red wire
(PS) and blue wire (ACN), the normal resistance is about
150
to 190 .
3. If the measured resistance is not correct, it means the
pump coil is broken or connector is loose. In this case, we
should check the connection first. If the problem hasn’t
been solved by re-connection, we should replace the
drain pump.
4.If the resistance is OK, but it also can’t work, maybe the
magnetism is too weak, so we need to replace the drain
pump.
